Great program BUT I have one problem. When I view the rips on my Popcorn hour I get lag between the video audio and subtitles. When I watch it on my computer its fine. Any suggestions why this happens and is there any way to tweak this?

I’m not really sure what you’re trying to do vis a vis encoding. undvd can encode video to pretty much any codec supported by mplayer/mencoder at arbitrary resolution and bitrate. So if you wanted to shrink a dual layer dvd down to 4.3gb I imagine you could do that although I’ve never done such a thing.

I’m not familiar with the software you mention so I have no idea what your custom is.

I’m on a strict Ubuntu diet, but I still have an XP VM running to do DVD rips and re-encoding (via DVD-Rebuilder) to get them onto a single layer DVD-R (or +R).

Would undvd do something similar? My goal is to, using Ubuntu, take a purchased DVD (dual-layer), strip off the encryption (via libdvdcss) and compress it down to 4.3GB (with our without menus depending on compression level required). I would then burn the resulting .ISO (or set of files in a VIDEO_TS folder) to a blank DVD.

Ideally, this process would re-encode (via HC Encoder or similar) and not transcode (ala DVDShrink). I’m patient and can wait for re-encoding.

Is something like this possible with undvd? If not, any suggestion on what products for Linux would do this? Command-line is fine. I just want something that works well and is consistent.

Thanks,

Thank you, that was fast I can confirm it worked fine. Very nice and easy to use and good quality results on my 4.4gb .iso’s The only thing i’d prefer is a separate srt file but that’s easy enough to create elseware.

Well, undvd is not made for that purpose, it is meant to be a fuller pipeline than that. But there is a program called vobcopy (and indeed undvd uses it internally if you tell it to) that does exactly what you’re asking. As far as decrypting goes, I believe the general rule is you want libdvdcss installed. And if it’s there then both mplayer and vobcopy will use it.

Is this tool capable of just ripping a copy protected dvd? ie, no transcoding to avi & altering the files etc.

Anyone who’s used dvd-decrypter on windows in the past knows what I mean. It would be incredibly useful to be able to copy the VIDEO_TS directly from disc to hdd. Then is can be burned to a dual-layer disc as is, or compressed to burn to a 4.7 GB dvd, or stipped of menus, or converted to avi if that’s your thing.

At the moment I’m still using windows app’s running via wine to do things like that (DVDFab to rip and DVD2One to compress). So far I cannot find any native tool that can do those tasks.

You’ve found a bug. Thanks!

I’ve just rolled out 0.7.5 which has the fix.

Yes I understand, your help file is very clear. But on my net book with NO dvd drive undvd would not run as it couldn’t find the drive.

Only after I connected my external drive did it run. Even though I was converting from an already existing .iso and the external drive was not being used.

I’ve just got back from work and both the rips have finished. Very happy with the results. The subs seem burned in as I couldn’t switch the on and off. I’ll have a proper play later, but I really like it. Thanks.

That message comes up because undvd assume you want to rip from a dvd disc. You can also pass -i (or –iso) or -q (or –dir) to rip from an iso or a directory instead of a disc.

Hi. Working well on my already ripped .iso’s. I tried it on my samsung nc 10 netbook running Debian. I needed to plugin my external usb DVD drive before it would start. I got “The device /dev/dvd doesnot exist” and “Supply the right dvd device to undvd….” I’m not sure if there is a way to disable the need for a for undvd to run without a DVD device present or not but though I’d mention it.

Thanks
